PINUS LONGIFOLIA/CHIR PINE/PINUS ROXBURGHII


     GENERAL DISCRIPTION

    The Chir Pine (Pinus roxburghii)
    named after William Roxburgii, is
    a pine native to the Himalaya. The
    range extends from northern
    Pakistan (North-West Frontier
    Province, Azad Kashmir), across
    northern India (Jammu and
    Kashmir, Punjab, Himachal
    Pradesh, Uttarakhand, Sikkim)
    and Nepal to Bhutan. It generally
    occurs at lower altitudes than
    other pines in the Himalaya, from
    500-2000 m, occasionally up to
    2,300 metres (7,500 ft).
    Chir Pine is closely related to
    Canary Island Pine, Turkish Pine
    and Maritime Pine, which all share
    many features with it. It is a
    relatively non-variable species,
    with constant morphology over the
    entire range.
   LOCATION
    This tree is located on a mound at
    POLYTECNIC FACULTY in JAMIA MILLIA
    ISLAMIA.




   BOTANICAL NAME
    Pinus longifolia or Pinus Roxiburghii
                                                  JAMIA POLYTECNIC LAWN


   SCIENTIFIC DISCRIPTION
    KINGDOM : Plantae
    GENUS   : Pinus
    SPECIES   : P.Roxburghii



   COMMON NAME
    Chir pine, Imodi pine; Chinese: xu mi chang
     ye song
     The species comes closer than any other
     other pine to being deciduous, having a
     needle retention time of one year, the
     shortest of any pine.
   FORM & HEIGHT
    It is a large tree reaching
    30-50 m with a trunk diameter
    of upto 2 m, exceptionally 3 m.


   DETAILED DISCRIPTION

    TRUNK/BARK/BRANCHING:It
    is a large tree reaching 30-50 m
    with a trunk diameter of up to
    2 m, exceptionally 3 m. The bark
    is red-brown, thick and deeply
    fissured at the base of the trunk,
    thinner and flaky in the upper
    crown.

    LEAVES:The leaves are needle-
    like, in fascicles of three, very
    slender, 20-35 cm long, and
    distinctly yellowish green.

    FRUIT:The cones are ovoid
    conic, 12-24 cm long and 5-8 cm
    broad at the base when closed,
    green at first, ripening glossy
    chestnut-brown when 24 months
    old. They open slowly over the
    next year or so to release the
    seeds, opening to 9-18 cm
    broad. The seeds are 8-9 mm
    long, with a 40 mm wing, and
    are wind-dispersed.

   USES
• The aromatic wood of Pinus longifolia is
used in Hindu medicine. The tree yields
an oleo-resin called sarala drava, srivasa
and kshira in Sanskrit. In the vernacular
it is called gandha-birozd.
• The wood of Pinus longifolia is
considered stimulant, diaphoretic and
useful in burning of the body, cough,
fainting, and ulcerations; it is generally
used in combination with other
medicines.
• The oleo-resin or crude turpentine is
used in the preparation of plasters,
ointments, and pastiles for fumigation. It
is applied to buboes and abscesses for
promoting absorption.
•This species of pine tree reaches a large
girth, the bark forms flat patches which
can be broken off in chunks (of about 8
inches square by 2 inches thick ). It has
a layered structure like plywood, but the
individual layers have no grain. The
locals use this easily carvable bark to
make useful items like lids for vessels.
Blacksmiths use this bark exclusively as
the fuel for their furnaces.
• Old trees which die from fire or drying
out, undergo some metamorphosis in
their wood due to the crystallization of
the resin inside the heart wood. This
makes the wood become brightly
colored (various shades from
translucent yellow to dark red) and very
aromatic with a brittle, glassy feel. This
form of wood known as Jhukti by the
locals is very easy to ignite (It never
gets wet or waterlogged). They use it
for starting fires and even for lighting,
as a small piece of this burns for a long
time (owing to the high resin content).
• The dried needles of this tree forms a
dense carpet on the forest floor, which
the locals gather in large bundles to
serve as bedding for their cattle, for the
year round. The green needles are also
used to make tiny hand brooms.


    USES IN LANDSCAPE

• It is used as an ornamental tree,
planted in parks and gardens in hot dry
areas, where its heat and drought
tolerance is valued.
